To all whom it may concern;

vBe it known that I, SAMUEL D. BARR, a citizen of the United States, residing at Beach City, in the county of Stark and State of Ohio, have-invented a new and useful shaft and one of the agitating Self Rising -Flour Mixing Machine, of which the following is a specification.

My invention relates to improvements in self rising flour mixing machines.

The objects of the present inventionare, first to construct a simple device, and se c 0nd, to so arrange the parts that the various ingredients can be quickly and thoroughly mingled or mixed. Y

These objects, together with other objects readily apparent to those skilled in the art, may be attained by the construction illus- .trated in they accompanying drawings, al-

though the invention may be embodied in other forms, the construction illustrated bemg chosen by way of example.

In the accompanying drawing:

t Figure 1 is a longitudinal vertical section.

Fig. 2 is a transverse section on line 22, Fig-,lIp' Fig, 3 is a transverse section on line 3 -3, Big. 1, except the flour lifting buckets are not shown.

Fig. 4: is a detached View of one of the flour sprcaders.

Fig. 5 is a view showing a portion of the and conveying blades and its collar, also showing a portion one. of the outer conveying blade arrying arms.

Similar numerals of reference indicate correspgnding parts in all the figures of the drawings.

. In the accompanying drawing, 1 represents the flour or stock containing chest, which'within itself is of the usual construction, except in so far as properly arranging the various parts pertaining to my inventhe pulley 5, by means of which rotary moblades 9 can be so tionis imparted to the shaft 3, together with the different parts attached thereto by a suitable driving belt; but it will be under-- stoocl'that it is immaterial as to the specific kind ofgearing employed t impart this retary motion. Upon the shaft 3 are located a series of collars 6 arranged in abutting relation, which collars are provided with the combined agitating and conveying blades 7 said blades being directly connected at their bases to said collars, and being so inclined that they will move the material contained in the chest in a longitudinal direction with reference to the chest,

To the collars 6 are also attached thearms or spokes 8, to the outer ends of which are secured the agitating and conveying blades 9. The spokes or arms 8 are formed of such a length that the. agitating and conveying arranged to come in close relationship with the bottom 2-; by which arrangement all of the material contained in the chest willbe acted upon.

For the purpose of tudinalrnovements to the material the agitating blades and 9 are set at different angles so that-one set of blades will convey the material in onedirection and the other set of blades convey the material in the opposite direction, by which arrangement a comimparting two longipound longitudinalmovem'ent is produced,

and'at the same time a rotary agitating movement takes place. For the purpose of I better agitating the material and at the same time more thoroughly mingling the ingredients I provide a series of spreading blades 10, which are securely connected to the arms 8 by means of the heads 11 and the set screws 12 or their equivalents. noted that the spreading blades 10 are V- shaped and are so shaped for the purpose of better spreading and mingling the different ingredients acted upon.

For the purpose of liftingthe material vertically l proyide a series of buckets 13, which buckets are located at the delivery end of the chest. It will be understood that as-these buckets are rotated they will gather the material and by their continued rotation vertically lift the same and cause the It will be material located in the lower portion of the chest to be carried up and dropped-in the marily to the proper mixing of ingredients such as are commonly used in the manufacture of self-rising flour it is obvious that dif ferent grades of flour or dii'lerent kinds of flour can be properly mixed or blended. It will be understood that the collars 6 should be so connected to the shaft 3 that there will be no relative movement as between said collars and the shaft and in order to prevent any loose movement of the collars 6 upon the shaft 3, the grooves 14: are provided and the inner ends of the arms 8 seated in the grooves 14-, by which arrangement the collars 6 are securely mounted upon the shaft 3.

In use the desired quantity of flour and the various ingredients desired to be mixed with the flour are placed in the chest in the usual manner.

For the purpose of discharging the mixed orblended material the bottom 2 should be provided with a suitable delivery spout 15, which delivery spout is provided with the usual cut-off valve l6. During the time the material is being mixed, the delivery spout should be closed, but after the material has been agitated a sullicient length of time the delivery spout is opened and the material permitted to be conveyed to any desired place, preferably to sacks. By providing two sets of combined-agitating and conveying blades and locating these sets concentrically with reference to the shank, and by pitching the blades in opposite directions the material will be alternately moved longitudinally orfrom one end of the chest to the other, the central. portion of the material in one direction and the outer portion of the material in the opposite direction.

It will be understood that the pitch of the blades 9 should be such that the material will be conveyed toward the delivery spent 15 so that when the same is opened all or practically all of the material contained in the chest will be brought into proper position to he delivered.

It is Well undcrstobd that in the manufacture of self rislng l'lour various ingredients are employed such as phosphate, soda and salt and it is of utmost importance that these various chemicals be thoroughly mixed in order to bring about the best results. I have learned from experience that to thoroughly mix the ingredients about ten minutes is required and during this ten minutes of action the delivery spout 15 should be closed by means of the cut-off valve 16, but after the material has been agitated for about the time above pointed out the cut-oil valve can be opened and the machine left in action, whereby practically all of the material is removed.

For the purpose of adjusting the com-- bined agitating and conveying blades 9 upon the arms 8, the outer ends of the arms may be screw threaded, by which arrangement accurate adjustment can be made; and afterto the collars, and so adjusted that the inner ends of said arms will be properly seated in the longitudinal grooves 14.

I claim:

1. In a mixing machine of the character specified, the combination, with a mixing trough; of a horizontal shaft rotatably journaled therein; a series of collars mounted upon said shaft in abutting relation and provided with openings extending radlally therethrough; radial arms seated in said openings; a set of agitating blades secured to the outer ends of said arms; and a set of agitating blades connected at their bases directly to said collars the firstand secondnamed sets of blades being pitched at difi'erent angles so that the said second-named blades will. convey the central portion of the 5 material acted upon toward one end oftho trough durin the rotation of said shaft, while the said first-named blades will 0011- vey the outer portion of the material toward the other end of the trough, and both sets will simultaneously subject it to a rotary agitating movement.

In a mixing machine of. the character specified, the combination, with a. mixing trough; of horizontal shaft rotatably journaled therein; a series of collars mounted upon said shaft in abutting relation and provided with openings extending radially thercthrough; radial arms seated in said openings; a set of agitating blades secured to the outer ends of said arms; a set of av itating blades connected at their bases irectly to said collars, the firstand second named sets of blades being pitched at different angles so that the said second-named blades will convey the central portion of the material acted upon toward one end of the trough during the rotation of said shaft, while the said first-named blades will 0011+ vey the outer portion of the material toward the other end of the trough, and both sets will simultaneously subject it to a rotary agitating movement; and a set of spreading blades atlixcd to said arms between the first-named set of agitating blades and said collars.

3. In a mixing machine of the character specified, the combination, with a mixing trough; of a horizontal shaft rotatably journaled therein; a series of collars mounted upon said shaft in abutting relation and provided with openings extending radially therethrough; radial arms seated in said openings; a set of agitating blades secured to the outer ends of said arms; a set of agitating blades connected at their bases di rectly to said collars, the firstand secondnained sets of blades being itched at differ-t ent angles so that the sand second-named blades will convey the central portion of the material acted upon toward one end of the trough during the rotationof said shaft,

While the said first-nan1ed blades will convey the outer portion of the material toward the other end of the trough, and both sets Will simultaneously subject it to a rotary agitating movement; and a set of spreading; 15

blades of V-section affixed longitudinally to said arms between the first-named set of agitating blades and said collars.

In testimony that I claim the above, I have hereunto subscribed my name.
